Suppose the following amino acid chain was created based on a student's transcription and translation: tyr-leu-pro-met in the chain, which data show a possible source of error? explain the error.

The position of Met seems incorrect.

The amino acid sequences of all proteins begin with Met because it is the amino acid that is attached to the anticodon for the AUG start codon.

It looks like the student might have worked in a backward direction for transcription.

Explanation:

Those are the three reasons edge provided for this question

The position of Met (methionine) in the amino acid chain created based on the student's transcription and translation is wrong.

Methionine always is at the beginning of every amino acid chain obtained from translation because it is the amino acid that is coded for by the translation start codon, AUG.

Transcription is the process by which the information in the DNA coding for a gene is copied to make an RNA molecule, the mRNA, which is used in the synthesis of the gene product, for example a protein.

Translation is the process in which the information stored in the mRNA is used to synthesize proteins by the ribosomes.

The information in mRNA is read as a triplet of nucleotides known as codons by the ribosome. Each codon codes for an amino acid. The start or initiation codon is AUG and it codes for methionine. Therefore, every amino acid obtained from translation initially starts with a methionine.

In the amino acid chain created by the student however, methionine (Met) is found at the end of the chain. Therefore, it is possible the student translated backwards to obtain the amino acid chain he did.
